Quick Answer
Use the Yankee Funnel to pour darkroom chemistry from storage bottles into mixing containers or graduates with minimal spillage. Its wide 16 oz capacity and tough polyethylene build make it a dependable tool for film developing and chemistry transfer.
Why a dedicated funnel matters
Pouring chemistry by hand often leads to drips, splashes, and wasted solution. A funnel designed for darkroom work, like the Yankee Funnel, keeps the stream contained and reduces the chance of contamination between different chemicals.
The 16 oz size is practical for most darkroom tasks, from mixing a liter of developer to pouring working solution into a tank. Its polyethylene construction is chemical-resistant and easy to rinse between uses.
Trade-offs to consider
The Yankee Funnel is not designed for precise measurement—it is a pouring aid, not a graduate. You will still need a measuring cylinder or scale for accurate chemistry ratios.
Because it holds 16 oz, it is best for smaller transfers. For larger volumes, you may need to pour in batches or use a wider funnel.
Step-by-Step: Using the Yankee Funnel
- Set up your workspace: Place the funnel securely in the neck of your receiving bottle or graduate. Make sure it sits straight and does not wobble. Use a clamp or hold it with one hand if needed. Check that the funnel is stable before pouring to avoid sudden spills.
- Pour slowly and steadily: Pour the chemistry from the source container into the funnel at a moderate, controlled rate. Do not fill the funnel to the rim—leave headspace to allow air to escape. If you see liquid backing up in the funnel, pause and let it drain before adding more.
- Rinse between chemicals: After each use, rinse the funnel thoroughly with water (or the appropriate rinse solution) and let it dry. This prevents cross-contamination between different chemistry. Never mix different chemicals in the funnel without cleaning it first.
- Store properly: Keep the funnel clean and dry when not in use. Store it away from direct sunlight and extreme heat to prolong its life. A dry funnel is less likely to harbor residue that could affect future mixes.
